The construction of some large industrial units and their endowment with oversized and heavy technological equipments, as well as their regular repair or replacement, led to the necessity of transporting some parts that exceeded both the gauge and the tonnage admitted on public roads.
The choice of the route and the transport scheme (on one or more trailers) was made in such a way that requests would be as few as possible in order not to exceed the carrying capacity of the roads and bridges.
However, in many cases the calculation requests overcome the admitted ones, sometimes requiring in some situations the consolidation or even the reconstruction of bridges to respond tothese increased requests.
Thus, the circulation of convoys with a width or height of up to 7 to 8 m and with a weight of up to 600 tons came to be ensured.
But the repeated passage of the heavy convoys on the same routes can lead to road deterioration. Because of this, exceptional load classes were placed within the standard; these are to be taken into considered by beneficiaries in the case of bridges located on routes where the frequency of heavy transport is high.
